I would like to know if it's better to buy a RPi or a computer. I think you're going to find that most members on this forum have both. I use my RPi's for writing programs to control things with RPi's. If I want to do just about anything else (browsing, office applications, circuit design/simulatio...

Raspian is not a real time operating system and the OS will sometimes swap out a process to do other things that are either higher priority or are at the same priority but haven't gotten their share of CPU time.

2- I do not know what to do with the open end cable at bottom. If you're referring to the wire dangling from the bottom of the 4.7k resistor, connect it to GND 3- I am not sure what tolerance resistors should be. I think I can find 10% ones in the market as usual. 5% and 1% should be more common th...

How do you know in advance if a site or application is untrustworthy? The big hole - Javascript - is that not almost everywhere? If so, avoiding it would essentially require giving up the use of graphical internet browsers. You can start by disabling Javascript in your browser. When some site needs...

I’m excited for the release of the new raspberry pi but I’m sad that the CPU it has is vulnerable to meltdown and spectre as the previous pi was not Any microprocessor that employs speculative execution to improve performance is susceptible to those attacks. If you want to avoid that, then you need...

So is there a way I can make the GPIO pins more strongly secured by the pi? More secure than what? What are you currently doing? And is there any way I can prevent the pi from getting burnt or fused? Don't overload any outputs, operate inputs within specifications, don't short things. Also, I was r...

If it were me, I'd copy Raspian to a new SD card. Boot to it and mount your original SD card with a USB adapter and copy the important files to the new card. Then, before doing anything significant in the future, back up the image. Also make backups of your work whenever you do something you don't w...

So, it wouldn't be wrong for me to make an image backup of that uSD card for safety, and then to reformat it and using Etcher to put Raspbian on it? I would guess that this would give me pretty much the same thing as on my first RPi, which I got less than 2 weeks ago. If you like how you have your ...

Especially it's would be great to know what is the size of CMOS transistor (in nm). It's unlikely that they only used one transistor size. The smallest transistors will be in the memory array and they're typically smaller than any logic transistors because the array is very regular and they can opt...
